Application filed January 1s, 1923; semaine. claus.

To all whom t may concern:

Be it known that I, DAVID zen of the UnitedStates, residing at Chicago,in the county of Cook and State `of Illinois, have invented new anduseful Im-` provements in Arch Supports, following is a specification.

This invention relates to an arch support and has for its primary objectthe construction and arrangement of parts whereby the bones of the footwill be properly acted upon to rectify any displacement or distortion ofthe bones of the foot. v l

An object of the invention is the use vof an auxiliary support that maybe quickly arranged in place for co-action against the metatarsus bonesindependently of the main arch-supporting elements.

Another object of the invention is the combination of two supports, amain and auxiliary7 which may be used together or independently. t f

Besides the above my invention is distinguished in the manner of shapingthe auxiliary support and connecting the same to the main support. v

IVith these and other objects in view the invention will be betterunderstood from the following detailed description taken in connectionwith the accompanying drawing wherein:

Fig. 1 is a top plan view of the support with part of thecover brokenaway.

Fig. 2 is a bottom plan View.

Fig. 3 isa longitudinal sectional view on the `line 3-3 ofFig. 1.

Fig. 4 is a top plan view of the auxiliary of which the Fig. 5 is alongitudinal sectional `view of the auxiliary support.

Fig. 6 is a top plan view of a modified form of the invention.

Fig. 7 is a detail section on the line 7-7 of Fig. 6.

Fig. 8 is a plan view of the auxiliary support;

Again referring to the drawing the nu' meral 1 designates in itsentirety an arch support as constructed in one of my copendingapplications known In this application as the main support, consistingof a base plate 2 and arch supporting plates 3 and 4 which are bowed andetachably engage clips 5 connected to the base. Ihese elements areidentical in construction as ldevbase scribed in my co-,pendingapplication, Serialx No'. toae'aa-fiied ySra-anita ai, 1921, with theexception that the clip is provided with, a recess 6. j l o f Myimproved auxiliary support' 7 which is shaped 'andarranged toyexertf'p'ressure against the metatarsus bones of the footand.

more particularly at the point of connection f with the phalangesl bonesof the foot is of convex formation to increase the effective actionthereof. In this particular case the auxiliary support is stamped fromsheet metal toV have a tongue 8 that is passed around the forward edgeportion ofthe base plate with the extreme end positioned in the recess6. l`,It Vwill be noted that the forward end portion of the auxiliarysupport rests upon the spring plates 3 and 4 and as a result acertaindegree of resiliency is given to the auxiliary support and this actionis increased by the novel manner of forming the torligue 8 andconnecting same to the p ate. f In Figs. 6, 7 and 8 of the drawings 'amodiied form of the auxiliary support is shown lin which the main convexbody 20 of the auxiliary support 21 is surrounded by a substantiallyfiat iiange 22. Laterally projecting abrupt shoulders 23v are formed vonthe flange 22 at diametrically opposed points and they are adapted toengage against rivets 24yof the arch support structure for maintainingthe auxiliary support in proper position, the shoulders 23 replacing orserving a similar vfunction to the tongue which is formed on theauxiliary support 7.

oor'

vFrom the foregoing description talreniin i connection withtheaccompanying drawing it will be apparent thatI provide a support of twomain elements that may act independently or jointly to properly restorethe bones of the foot to normal position.'

It will also be noted that the auxiliary support may be removed atwillpand different sized auxiliary supports substituted. Ity will alsobe noted the connection is such that slight adjustment may beaccomplished.

Thus it will be seen that I provide a support that may be readily shapedand adjusted to various shaped feet so as to properly correct the same.

It is, of course, to be understood that the various parts may be shapedin other mane ners and the auxiliary support constructed 4 of othermaterials than sheet metal and may he shaped in various other mannersand, therefore, Iy do not desire to be limited in any manner except asset forth in the claims hereunto appended.

Having thus described my invention what plate, arch supporting platesyieldably con-A nected to the base plate, and means or engaging themetatarsus bones of the :toot and detachably connected to the base plateand further having yieldable movement assisting the yieldable action ofsaid arch supporting plates.

8. An arch support comprising a. base 20' plate, yieldable archsupporting plates connected thereto, and` an auxiliary support havingone end portion yieldahly engaging said plates, and its other endportion yield'- ably engaging the base plate.

4. In combination with an arch Support inclu-ding a base plate andyieldable arch supporting plates, an auxiliary'supportl having a tonguedetachably engaging the base plate, said support yieldaloly4 engagingthe-80 said' arch supporting plates.y

In testimony whereof I aflix my signature.

DAVID GRANT.
